Dear Stovers,
The lab work is developing stoves to use modified wood for the purpose to clean the air. That’s good. The fuel is supplied along with the Air Burner. Then a stove designed to burn native biomass and cook a meal is placed along side the Air Burner and happens to create a little puff of smoke - not to worry. The smoke is quickly taken up by the Air Burner and the air remains clean so to enjoy a nice healthy meal. Thats what we are doing.
Regards
Frank

> This webinar <https://attendee.gotowebinar.com/register/6749480047610317058> will provide background on how stove emissions can be related to concentrations of indoor air quality and vice versa. The modeling approach to be described is the same as that used for the development of the emissions guidance in the International Workshop Agreement 11:2012: Guidelines for evaluating cookstove performance <https://www.iso.org/obp/ui/#iso:std:iso:iwa:11:ed-1:v1:en>; and the WHO Guidelines for Indoor Air Quality: Household Fuel Combustion <http://www.who.int/indoorair/guidelines/hhfc/en/>.

> In addition to describing how the model can be used to estimate air quality or derive emissions targets, the presentation will include background on the WHO’s work on providing guidance in the household energy sector and planned future activities. These future activities include expanding the model’s capabilities (e.g., accounting for stove stacking), as well as providing an interactive web version of the model for which regionally-based data can be input for more relevant local application. The webinar will conclude with a discussion on policy implications, and the interpretation and application of performance targets.

>> "However, while emission rate and indoor concentration are mechanistrically linked, indoor concentrations from episodic sourcese are not meaningfully linked with respiratory intake or uptake.4 The implicit assumption of today’s standards is that a cookstove with lower emission rates will lead to lower indoor concentrations of pollutants and will therefore be safer for the user. However, this assumption is not necessarily true."
